A geometric multiplication large-force two-dimensional multi-stage double-connecting-rod lever manpower aircraft is characterized in that a group of geometric multiplication large-force two-dimensional multi-stage double-connecting-rod levers are arranged on the right side of a bracket, multiple stages can be two, three, four, five or more stages, the last stage of lever is connected with an upper transmission turning rod, and the lower part of the upper transmission turning rod is fixedly connected with an upper inclined push rod and a lower inclined push rod. When a user steps on a pedal to drive a transmission turning rod and a box paddle to beat air towards the lower right, the box paddle obtains pushing force towards the upper left portion, the pushing force is transmitted to a double-connecting-rod and a turning rod support through the transmission turning rod, and when the geometric multiplication large-force two-dimensional multi-stage double-connecting-rod lever parallel support is driven to move upwards, an upper transmission turning rod and a lower inclined push rod are driven; and then the upper bracket is pushed to make the man-powered aircraft move forwards. The large-force effect is achieved through the geometric multiplication large-force two-dimensional multi-stage double-connecting-rod lever. The double-connecting-rod longitudinal and transverse two-dimensional arrangement makes full use of space. The invention has the advantages of firm structure and large strength.

    一种几何倍增大力二维多级双连杆杠杆人力飞机,支架右边设有一组几何倍增大力二维多级双连杆杠杆,多级可以是2、3、4、5或更多级,最后一级杠杆连接设置上传动拐杆,上传动拐杆下部固定连接上下斜推杆。当脚踩脚踏带动传动拐杆、箱桨向右下方拍打空气时使箱桨获得向左上方的推力,该力经传动拐杆传给双连杆、拐杆支架,带动几何倍增大力二维多级双连杆杠杆平行支架向上方运行时,带动上传动拐杆、下斜推杆,再推动上支架使人力飞机前行。本发明通过几何倍增大力二维多级双连杆杠杆达到大力效果。双连杆纵向横向二维设置充分利用空间。本发明的优点:结构结实,力量大。
